Detailed Comparison: Kohler vs. American Standard Toilets

Material of Construction

One thing you can expect from both Kohler and American Standard is durable construction. Most of their residential toilets are made from vitreous china, a glazed ceramic material that resists moisture and everyday wear.

With proper use and maintenance, a quality ceramic toilet can last for many years. However, components such as fill valves, flush seals, and handles may need occasional replacement.

Both companies also manufacture toilets with smooth glazed surfaces that are relatively easy to clean.

Verdict: In terms of basic ceramic durability, Kohler and American Standard are closely matched.

Design

Both brands manufacture attractive toilets, but Kohler has a slight edge when it comes to design variety. Whether you’re searching for a contemporary toilet or a traditional model, Kohler offers plenty of options.

Kohler collections such as Cimarron, Memoirs, Santa Rosa, and San Souci provide different styles, bowl shapes, and finishes.

American Standard also offers stylish options through its Cadet, Champion, and Studio collections. Its designs generally focus on practicality, comfort, and ease of cleaning.

Ultimately, the best choice depends on your bathroom style and personal preference.

Flushing Performance

Flushing performance is one of the most important factors when comparing Kohler vs. American Standard toilets.

American Standard is known for its Champion 4 and Cadet flushing technologies. The Champion 4 features a large 4-inch flush valve and a 2-3/8-inch fully glazed trapway designed to move waste efficiently.

Kohler uses technologies such as AquaPiston, Class Five, and Revolution 360. The AquaPiston canister allows water to enter the bowl from multiple directions, creating an effective gravity-powered flush.

Both manufacturers offer toilets capable of clearing solid waste in a single flush under normal conditions. However, performance varies by model, water volume, and trapway design.

For a more accurate comparison, check independent MaP flushing scores and the specifications of each model.

• Large 4-inch flush valve supports effective waste removal.

• EverClean surface helps reduce stains and buildup.
• Elongated bowl provides additional seating room.
• Slow-closing toilet seat included.

Cons:

• The 1.6 GPF model uses more water than 1.28 GPF toilets.
• One-piece construction makes the toilet heavier to handle.
• May cost more than basic two-piece models.

The Champion 4 is a good option if strong flushing performance is your priority. However, homeowners seeking maximum water savings should compare American Standard’s 1.28 GPF models.

Ease of Cleaning

Cleaning depends partly on whether you choose a one-piece or two-piece toilet. One-piece toilets are generally easier to clean because there is no gap between the tank and bowl.

American Standard offers EverClean surfaces on selected models. This finish helps reduce the buildup of stains and odor-causing bacteria.

Kohler also provides cleaning-focused features, including CleanCoat treatments and ContinuousClean technology on certain models.

Additionally, Kohler’s Revolution 360 system creates swirling water movement to improve bowl rinsing.

Neither brand is completely maintenance-free. Regular cleaning is still necessary to prevent mineral deposits and staining.

If you want fewer exterior surfaces to scrub, consider a one-piece toilet or a model with a skirted trapway.

Kohler Cimarron Comfort Height Toilet: Technical Specifications

The Kohler Cimarron is another popular choice, especially for homeowners who prefer a comfortable seating height and a powerful flushing system.

The specifications below refer to the Kohler Cimarron K-5310, a two-piece elongated toilet with a skirted trapway.

• Elongated design may require additional bathroom space.

Ease of Installation

Both American Standard and Kohler toilets can be installed using standard plumbing methods. However, the difficulty depends on the toilet design.

Two-piece models are usually easier to handle because the bowl and tank can be moved separately. One-piece toilets are heavier and may require assistance.

Kohler’s ReadyLock system simplifies installation on selected skirted models. American Standard also offers conventional mounting systems that are familiar to many plumbers.

Before purchasing either brand, check the rough-in measurement. Most residential toilets use a 12-inch rough-in, but 10-inch and 14-inch models are also available.

Our toilet rough-in calculator can help you understand the required measurement.

Comfort

Kohler is well-known for its Comfort Height toilets, which provide chair-height seating. These models can make sitting down and standing up easier for many adults.

American Standard also offers comfortable chair-height toilets through its Right Height and other collections.

Both manufacturers provide elongated bowls, which generally offer more seating room than round bowls.

For shorter users and children, however, a standard-height toilet may be more comfortable. Compare actual seat heights instead of assuming a taller toilet is always better.

Price

Price is another important consideration. American Standard often offers competitively priced toilets, particularly within its Cadet collection.

Kohler also has affordable models, although some premium designs and specialized finishes cost more.

Remember to include the cost of a toilet seat, wax ring, supply line, and professional installation when comparing prices.

• Variety of designs to fit different bathroom styles.
• Some models feature innovative flushing systems for better cleanliness.

Cons:

The only complaint that American Standard users have had about their flushing systems is the sticking of substances at the back of the toilet. Some American Standard flushing systems are not sufficient and leave waste marks after flushing. So, you may have to clean your toilet more often than expected.

Ease of cleaning

This depends on whether the toilet is a two-piece or one-piece unit. Generally, one-piece toilets are simple to clean than two-piece toilets. If you want a toilet that won’t give you a headache to clean, then consider going for a one-piece unit. Such toilets don’t have a gap between the tank and bowl where mold, mildew, and bacteria grow from.

When it comes to these two brands, you can say that American Standard toilets are easier to clean as most of them feature an EverClean surface, while Kohler doesn’t. The EverClean surface keeps the toilets clean for longer by preventing the sticking of stains and waste on the bowl.

However, even without a special coating, most Kohler toilets don’t allow substances to stick to the bowl. And that’s why you don’t hear people complaining about Kohler toilets being hard to keep clean. Actually, Kohler toilets are easier to keep clean as the AquaPiston flushing system pushes everything down the drain. This is not the same case with the class five flushing system, which tends to leave waste marks at the back of the toilet.
